1. Involved in a project entitled “Minimum Flow Requirements of River System for Ecology” A study has been conducted on water quality modeling in a stream to simulate the concentration of pollutant of conservative and non-conservative type. The study found the minimum flow requirements for maintaining the water quality standard from different considerations such as irrigation, drinking, bathing, industrial and maintaining the ecosystem in the river. In case industrial wastes are disposed the level of treatment and waste assimilating power of the stream is being also considered. The dispersion of various pollutants has been studied using Hybrid Cells in Series Model. The study carried out by predicting the status of water quality subsequently to find the minimum flow in river Brahmani, Orissa. Funded by : WAPCOS Gurgaon, IndiaStatus of the project : Completed My Role in the project: Co-Investigator.

2. Sustainability Solutions For iSimangaliso St Lucia Estuarine LakeiSimangaliso Wetland Park (Lake St Lucia) is South Africa's largest estuarine lake which has been recognized as UNESCO World Heritage Site. The river Mfolozi transports and deposits heavy silt load at the combined mouth of Mfolozi and St. Lucia. The salinity level dramatically increases during drought period. It is currently experiencing serious drought due to climate change and other factors; as a result ecosystem of the lake has got affected by loss of biodiversity. This project aims to develop models for inlet functioning of this unique system with the knowledge of sediment transport along Mfolozi river. It also aims to integrate biophysical response to assist with the sustainable management of the resource. This will help to ensure that the system continues to conserve the biodiversityFunded by : SANPAD, South AfricaStatus of the project : On goingMy Role in the project : Co-Investigator

Abstract of Ph.D Thesis: [A Study on Pollutant Transport in a stream]Considering non-equilibrium sorption of pollutant in each zone of the HCIS model, namely; plug flow and two thoroughly mixed zones of unequal residence time, a semi analytical solution for pollutant transport has been derived using Laplace transform technique. The hybrid cells in series model that incorporates adsorption (HCIS-A) is continuous in time and discrete in space. Response of the HCIS-A model closely matches with the finite difference solution of the differential equation governing advection dispersion and non-equilibrium adsorption. Considering first order decay at a specific rate, advection and dispersion, using HCIS model, the pollutant transport has been simulated. It is found that the concentration time profile derived from the hybrid cells in series model that incorporates decay (HCIS-D) matches with the analytical solution of advection dispersion decay equation model.Considering, decay of pollutant, re-aeration and advection dispersion transport in the HCIS model, an analytical solution has been derived for DO deficit. The response of the hybrid cells in series model that incorporate re-aeration (HCIS-R) closely matches with the numerical solution of Streeter-Phelps dispersion model. To demonstrate the flexibility of the hybrid models to incorporate decay and adsorption processes, C-t profiles have been computed using the field data of River Brahmani, in India.

Abstract of M.E Thesis: [An Analysis on Irrigation Water Pricing]Though our nation has a large supply of water it is not available at the right time and also adequate quantity is not ensured. To overcome this problem the water should be stored and supplied. Generally in most of the command areas the farmers are irrigating more than the required quantity of water to crops with the production of increasing the yield. Hence there exists a typical economic problem in allocating the irrigation water to the formers. An attempt has been made to analyze the agricultural production function and how it relates the inputs and outputs in order to determine the water pricing using the optimal quantum of water applied in the field. A production function curve has been drawn for the variable input (water) and to the corresponding output (yield). The second-degree polynomial equation is obtained and the optimal depth of water has been calculated by production and profit maximization approach with the use of controlled water saving method. And from this a method has been proposed to price for irrigation water.
